National Dental Hygiene

Certification Examination (NDHCE)



The National Dental Hygiene Certification Examination (NDHCE) measures the knowledge of new graduates from Canadian dental hygiene (DH) programs and internationally trained DH Professionals, against current national DH practice and educational standards.


The NDHCE tests the level of knowledge, judgment, and skills of Canadian Dental Hygienists that are expected at the entry-to-practice level. The NDHCE is constructed in such a way that it respects diversity in terms of culture, provincial/territorial regulations, language, and special needs. The process to develop the exam is thorough and includes checks and balances as well as multiple layers of review. The NDHCE is fair and meets or exceeds published technical requirements for standardization (the treatment of all candidates in a similar matter), reliability (consistency in measurement), and validity (measuring what we are supposed to measure).
